A Toronto-based tax preparer has been sentenced to 90 days in jail after pleading guilty to two counts of fraud, the Canada Revenue Agency (CRA) announced Wednesday.

The CRA reports that Carmine Sorella has been sentenced in the Ontario Court of Justice to a 90-day jail term, to be served on weekends, and 12 months conditional sentencing, after admitting to two counts of fraud over $5,000.

Specifically, the CRA says that its investigation found that Sorella claimed fictitious employment expenses and business losses, totalling $547,643, on 77 tax returns, in order to claim unwarranted income tax refunds for 42 of his clients. As a result, Sorella underestimated his clients’ federal income tax owed by approximately $108,459, it notes.
